Fitting an ISOFIX car seat

How does ISOFIX work?

ISOFIX car seats and bases have 3 ISOFIX points:

2 ISOFIX connectors (metal bars) fit on the anchor points (metal clips) at the base of the vehicle seat.

A top tether or support leg

The top tether anchor point is on the boot floor or the back of the seat bench. In most newer cars it’s highlighted with the top tether logo. The top tether hook of the car seat needs to be firmly attached to the hook, to secure the third ISOFIX point.

The support leg is on the floor of the car between the back and front seats (when installed on the rear bench) or between the front seat and dashboard (when installed on the passenger seat). To work correctly, the support leg of the car seat should be stable.

If you use a support leg, it is very important to check whether the floor of the car has a floor storage compartment.

If it has, you must check the car fitting list / instruction manual to see how you can use a support leg in combination with the compartment.
